Roger Federer, Microsoft’s Gates to play doubles for charity

SEATTLE — How’s this for a doubles team? Roger Federer and Bill Gates.

The 18-time Grand Slam champion and the billionaire Microsoft co-founder will pair up in a one-set exhibition match in Seattle on April 29 to support children’s education in Africa.

Federer and Gates will play against John Isner — the American who won the longest match in tennis history — and an as-yet-unannounced celebrity partner. Then Federer and Isner will square off in a best-of-three-sets singles exhibition.

Proceeds from the Match for Africa 4 will benefit the Roger Federer Charitable Fund and Roger Federer Foundation.
